Abstract
A disposable applicator for dispensing a desired quantity of a substantially non-runny medicant medicament, including a housing, a plunger and a replaceable cap. The housing is generally tubular having opposing proximal and distal ends and a tapered inner surface extending therebetween. The distal end terminates in a dispensing nozzle that defines a dispensing passageway in substantial coaxial alignment with the housing, while the inner surface has an alignment device. The plunger has a peripheral edge and is configured for axial movement within the housing, where the peripheral edge is aligned by the alignment device and slidingly guided by the inner surface, supporting the plunger therein. The plunger is configured for slidable advancement toward the dispensing opening by exertion of force by a user, so as to urge the medicament through the passageway.
